  • Non-steady state detector was added to HMC workflow
  • Reference image estimator for HMC was added:
    • If non-steady state is detected it will be used as a reference (they tend to have better tissue contrast)
    • Otherwise a median of 20 motion corrected volumes will be used as a reference
  • EPI skull mask reportlet was brought back
